The R2 Twin-Plot Rotary Combine is a game changer in the seed research industry. It operates at faster harvest speeds while producing less seed damage, cleaner samples, easier cleanout, and lower seed loss than competitive models. With two separate multi-speed independent rotor chambers, there is no side-by-side crossover and plot-to-plot carryover is undetectable. The self-cleaning, top-fed rotor design enables earlier harvest of large green plants, tough stems, and high plant foliage. With an increased harvest window, start harvesting plots earlier for faster advancement decisions. The Final Tier 4 275-hp Cummins engine and 4-wheel drive advanced torque king keep operations running at maximum efficiency while the premium R2 cab is designed for the unique needs of seed research professionals.
